I have a server with centos 6.5 installed and later upgraded to 6.6 after restart, installed kvm and created centos 6.5 as guest and later upgraded guest to 6.6. Now after host reboot i am not able to start guest as it shows "Internal error process exited while reading console log output Supported machines are: pc RHEL 6.5 pc RHEL 6.5.0 RHEL 6.5 pc RHEL 6.4.0 RHEL 6.4 pc " Even though by changing "Machine" in xml config from RHEL 6.6.0 to RHEL 6.5.0 vm has started and its working. But why is 6.6 guest not supported in 6.6 host,i suspect its because of some upgradation issue from 6.5 to 6.6.Can some one please help me understand this.
